I am facing a straing problem with programming the Roomba create tomove forward. Whenever I ask it to move x mm forward it seems to moveonly x-50mm forward. However when I ask it to move x mm backward itdoes so correctly.

Besdies this, the obstacle detection using bump(), bumpLeft() andbumpRight() do not seem to work for me.

Any suggestions ?

also is using the autoupdate feature in the RoombaComm constructor agood option to measure the distance moved by odometry ?M
